Small cells are redefining the traditional cellular system concepts. Coordination among small cells offers several benefits in terms of utilizing existing network infrastructure to support advanced interference management, mobility management as well as Self-OrgaNizing (SON) functions. In this paper, the problem of handover management is studied. The coordination between small cells is generally not considered in many existing handover management solutions resulting in increased handover cost, session interruption time and core network overload. To this end, a novel local anchor-based architecture for coordinated small cells is proposed in this paper, based on which three handover schemes are presented.
